Wow the sprites are fantastic, the I particularly love the background art. The effect for enemies teleporting back is really cool, everything contributes to the overall theme and really sells the whole cyberpunk aesthetic.
I like that there is a delay between punches meaning you have to time your attacks rather than just mashing the key, although I feel the timing needed to hit an enemy without being hit back is a bit too precise.
Overall I think you've got a good amount of challenge without overwhelming the player, I had fun playing it. Nice one!
